Today this is a marina for pleasure boats. In 1848 it was a working dock that admitted directly onto the Potomac River, and was the site of the largest non-violent slave escape attempt in US history, the “Pearl Incident”, when 77 individuals attempted to flee down the Potomac river and through the Chesapeake Bay with the intended destination of New Jersey, a free state. Their efforts were thwarted by contrary winds on the Potomac and betrayal by a fellow slave who did not join them.

These warehouses in Georgetown today house businesses, a tavern and boutiques, but at the time of the Pearl Incident were tobacco and grain warehouses owned by Mr. Dodge, the man who owned the leaders of the escapee contingent.

The net outcome of the Pearl Incident was the ending of the slave trade in Washington DC in 1850, but full abolition of slavery and legal emancipation would have to wait until 1862. Along the way, the captain and first mate of the Pearl spent four years in prison because they could not afford to pay the fines ($10,000 in 1848 currency, or about $250,000 in today’s currency).

The last two weekends, I’ve been teaching an Intro to Platinum/Palladium Printing class. In the past, I’ve only taught it from film negatives, but this time I did it with a module on making digitally enlarged negatives as well. It was a rousing success- I had a great time teaching it, and I had some very enthusiastic students, all of whom were very seriously interested in continuing with the medium.

Last week, we started out learning basic coating technique, talked a bit about paper selection, and the importance of a good negative to work from. To expedite the process, I provided students with negatives that were already processed for platinum/palladium printing.

This week we covered making images from digitally enlarged negatives. I had students bring in a selection of images on thumb drives and we picked one or two to make negatives with. Here are my assembled students with finished prints from our digital negative printing session. The prints are much warmer in color in this photo than they are in real life because I took this on my iPhone in mixed lighting.

Students holding prints

A better representation of some student prints. We also tried doing Ziatypes (a variation on palladium printing that is a printing-out process rather than a developing-out process, and by default has a much cooler, silvery tone to it than a pure palladium print does). The two images in the center row – left center and dead center – are Ziatype variations. The woman’s portrait was from a 40+ year old in-camera 8×10 negative not specifically developed for alt-process printing, but it worked quite well. The soft edges are from the fact that the negative was not processed archivally and is starting to silver out.

Having a little fun with the panoramic function on my iPhone in class today. Took this picture of two of my Large Format students doing studio portraits with a 4×5. I dug into the vaults and found some of my remaining stash of Polaroid Type 55 and let the students burn a couple sheets. I was more than pleasantly surprised with how well it worked- my Type 55 has to be a decade out of date by now, but the pods still processed nicely. I’d post some results but my students ran off with the negatives before I could copy any of them.

This was also my first test of my PocketWizard wireless flash sync setup on large format, and it worked very well. I got a little clamp from B&H photo that locks onto the front standard of my camera, and attached a hot shoe to PC adapter to the clamp. The PC cord connected the shoe to the sync on the shutter, and the PocketWizard sat in the shoe.

The other PW unit was connected to my Calumet Travelite monolight. This setup let me use my Sekonic L358 meter which has a PocketWizard trigger module, so I could meter wirelessly. That’s a big boon even when doing still life, and an even bigger one when shooting portraits, because that’s one less wire for you OR your sitter to trip over. If you look carefully at the front standard of the camera, you can see the PocketWizard module sticking out of the side in the photo.

OK- well, the title is a tad misleading – my class WAS sold-out with a wait list. I added additional slots to accommodate the wait list, and there is ONE additional spot left. If you’re interested, now’s the time to grab it before it’s gone. I will NOT expand the wait list again for this session. The class is my perennially popular Introduction to Platinum/Palladium Printing class, this time with an expanded digital negative how-to session. Based on the response, I’m also planning a fall Platinum/Palladium Printing Extended Project course that will provide a six-to-eight week guided seminar in printing.

Pyramids, Teotihuacan, Mexico

The pyramids at Teotihuacan in Mexico was originally shot on a 2 1/4 x 4 1/4 inch roll film negative from my Lomo Belair X/6-12, then scanned and printed on Pictorico Premium OHP to make a 4 x 8 inch print.

Stairs, National Gallery of Art, Washington DC

Ditto the above with this shot of the National Gallery of Art staircase in Washington DC.

Making a print is fun and easy.

Potassium Oxalate Developer – 15 years old and going strong!

A frequently asked question: what about your developer chemistry? You mix up your Potassium Oxalate, replenish it as needed, and filter it periodically. But you keep on using the same batch of developer forever, unlike silver gelatin paper developers which have a finite lifespan, regardless of usage.

Digitally enlarged negative

Here’s a digital negative printed on the Pictorico OHP transparency medium. Other printers will work, but the industry standard seems to be Epson Stylus Photo printers with Ultrachrome K3 inks (or newer). I’m using an Epson 3880 at the moment.

Exposed, undeveloped print

Here’s an exposed print from the negative shown above. An exposed but undeveloped print will show a “ghost image” of the finished print. The development process happens VERY fast, as you can see in the video below.

I’ve walked past this mural for years, and they re-do it every so often. The primary change from visit to visit is the color palette, but over time, major compositional elements change as well. I’m showing the previous version (circa 2013) and now both in black and white just to keep the comparison visually fair.

Black Boy, Garuda, B/W

The bird’s head on the right is a mosaic, originally including mirror fragments, now painted. I think the fisheye treatment in the first image works well because the mural already has a bit of a fisheye perspective to begin with.

Double-exposures, especially accidental ones, can be so much fun! You never know what you’re going to get, and how it will work out. Here I have two very different images layered one atop the other, both with my Mamiya RZ Fisheye lens. Had they been done with different lenses I don’t think this would have worked out so well.

I decided to treat myself to a lens toy – I got a Mamiya RZ Fisheye lens for my RZ67. It arrived this weekend and I took it on a walkabout in my neighborhood to put it through its paces. I especially wanted to try and do some shots that did not scream “shot with a fisheye” to see if it could be versatile enough to keep in my camera kit, or was it really a one-trick pony.

In this shot, it shows that you CAN use it for street documentary if you want. It’s still a challenge, though, with the distortion it brings to background subjects. And it forces you to get right up on top of your subjects – They were maybe five feet away from me.

Applied sensibly to architecture, it works. You do have to be extra careful that your horizons are level and square, or you will get wild distortion.

This is perhaps my favorite image of the shoot. Leading lines abound and the backlit subject with the sun in the frame create drama.

Selfie with the fisheye – with the sun behind me, it’s impossible to keep yourself out of the photo (or at least your shadow).
